Naval aviators are responsible for drawing a penis in the sky over Okanogan County, Wash., Navy officials said.

Residents of Okanogan County spotted the drawings in the sky Thursday, and some documented the phallic art on Twitter.

Update: Navy apologizes, grounds aircrew involved

Officials with the Naval Air Station Whidbey Island in Oak Harbor, Wash., confirmed to KREM 2 News that Navy pilots were responsible for the drawings.

“The Navy holds its aircrew to the highest standards and we find this absolutely unacceptable, of zero training value and we are holding the crew accountable,” Navy officials said in a statement.

One mother who took photos of the skywriting and spoke to the TV station said she was upset at the prospect of explaining the image to her children.

The Federal Aviation Administration, when the station reached out for comment, said they're powerless to act unless the incident poses a safety risk. An official also said the agency "cannot police morality."
